Title: Manufacture of semiconductor device
IPC: H01L21/768
Filed: 1992-03-30
Abstract: PURPOSE:To provide a method of manufacturing a one-time write type storage circuit device, which is simplified and is high in reproducibility and reliability. CONSTITUTION:A metal wiring 4 is connected to both ends of a polycrystalline silicon wiring 8 through a plurality of contact holes 6 and 7. After an electrical circuit is formed, a constant current source 10 is connected to this wiring 8 on the basis of the measured result of the characteristics of the circuit and the wiring 8 is heated. By the heating, polycrystalline silicon absorbs the wiring 4 through the holes 6 closer to the center of the wiring 8 and an alloy layer 9 is formed. Thereby, as the resistance value of the circuit is reduced and the ratio of the resistance of the circuit to the ON resistance of a transistor 11 for drive use is changed to an input signal (a), the outputs (b) of transistors 12 and 13 for comparative decision use are constanted at a low level.

Abstract: PURPOSE: To prevent a wet type cooling tower from lowering its operating efficiency due to the jamming of a filter by replacing a planar splash filler therefor and to reduce the cost of power required for forced draft through the filler.  
     CONSTITUTION: A square plate surrounded by a frame 2 is divided equally into four square plates similar in shape thereto, and one of square plate thus divided is mounted at one corner to thereby form a splash plate 3. Then, an opening is formed at the residual plate occupying 3/4 of the rest in area to thus form a planar splash filler. In order to arrange the fillers thus formed as a filler block in a cooling tower, a number of the fillers are joined in a plane within the frame 2 to thereby form a sheet of panel. Such panels are installed in laminate at predetermined interval in the cooling tower. Dropped water 6 collides with the splash plates 3 so that the splash water droples pass through the openings 5 to make contact with air raising through the openings 5 to thereby thermally exchange therebetween.
